Abstract
Concerning Natural Gas reserves all around the world, Syngas -as a product- was decided to be the most important intermediate cut. Transport difficulties, hazards and safety made main Energy suppliers to replace and Supply Methanol for production and Export. This policy changed the balance in Global consumption and production of Methanol leads to a serious change in its pricing. Polymer demand in industrial countries prepared a powerful desire for new Methanol to Hydrocarbon (especially Ethylene and Propylene) processes desire. Lurgi, first proposed a process generates Dimethylether at the first reaction, then converts it to alpha olefins (Propylene mainly) and a light liquid cut. Two main catalysts were used for this process were Gamma-Alumina and ZSM-5. This process was also modified to a direct synthesis form leads to Methanol to H.C. Mobil developed this process to a qualified process which was supposed to use a continuous regeneration fluidized bed reactor in 1977. This new developed process was later managed and redesigned by UOP. The main Catalyst used for MTO was SAPO-34 (Chabazite). After 2000 hours literature study, our team in Petroleum University of Technology started its work on MTO over alkali modified ZSM-5 leads to a main process study and finalizing the optimum reaction condition. Resulted paper was published in Fuel (Elsevier). Then promotion was performed using Se, Ce, K and Cs. Then SAPO-34 synthesis was finalized in 20 main methods and process was studied delicately. Finally, the best Catalyst batch and method was promoted using 12 main active metals
